RECEPTAGLE FOR FIRE-EXTINGUISHERS.

Specification of Letters Patent.

Patented July e, 1907.

n Application filed November 16,1905. Serial No. 287,558.

To all whom it may concern.'

Be it known that I, EDWARD D. ToMPKINs, a citizen of the United States, and a resident of Middletown, in the county of Orange andState of New York, have made and invented certain new and useful Improvements in Receptacles for Fire-Extinguishers, of which the following is a specification.

My invention relates to an improvement in tubes for containing a powdel` for use as a fire extinguisher, the object being to provide an article wherein and whereby the chemical or chemical compound contained therein, will be prevented from deterioration by admission of moisture. These chemicals or compounds, employed for the purpose above mentioned, are usually packed or stored witliin metal tubes, which by reason of the admission of moisture, especially in the case of those tubes used upon boats, buildings 0r other structures at or near the water, and also by reason of the sweating on the inner side or surfaces of the metal tube, in the course of time becomes greatly deteriorated, if not entirely or wholly unfit for use for the purpose for which it is designed.

With a view of preserving the chemical or chemical compounds contained within the tube, the invention consists in a metal -tube having fitted therein a lining of water or moisture proof material, preferably paper,

said inner tube or lining being preferably provided with an open upper end and closed lower end.

` The invention further consists in certain novel features of construction, as will be hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure l is a view in elevation of the inner tube or lining. Fig. 2 is a sectional view of my improved tube. Fig. 3 is a sectional view taken on 4the line 3-3 of Fig. 2, and Fig. 4 is a view in elevation of a modified form of the inner tube or lining.

Referring to the drawings, A represents a metal tube or cylinder, having securely fastened to its lower end the bottom B, and to its upper end the ring or flange C1, to which in turn is detachably fastened the cover C. Within this metal tube is fitted an inner or second tube D, having an open upper end E and closed lower end F, said tube being formed or constructed of a water or moisture proof material, preferably of paper, said tube or lining being of a diameter to nicely and tightly flt against the inner surface of the metal tube A, and thereby prevent access of moisture through the seams or joints in the outer metal tube, and also preserve the powdered contents of the article from moisture caused by the sweating of the metal. When thetube is formed in this shape, that is, with an open uppe end and closed lower end, it will be inserted within the metal tube prior to the attachment ofthe ring or flange C, but in those instances wherein it is preferable to first apply the sing or flange C1, I form the inner tube or lining as illustrated in Fig. 4, that is, the tube G is made by rolling the water-proof material upon itself, and of' such diameter that it will readily pass through the central opening in the ring C1. After being inserted in the metal tube, the lining G, will of itself, open until it fits tightly against the inner surface of the outer metal tube, the material being of such width that when fully expanded within the outer tube, the longitudinal edges of the material will butt against each other, or if desired, slightly overlap. When assembled in this way, it will of course be understood, that both the upper and lower ends of the inner lining will remain open.

In practice I have found that a tube so constructed will indefinitely keep or preserve the powdered contents in a dry state, even though subjected to an atmosphere highly charged with moisture, thereby overcoming the objection to this form of re extinguisher, urged against it by those using them at'or near the water.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

An improved receptacle for containing a chemical or chemical compound in powdered form, said receptacle consisting of an outer metallic tube having a permanent bottom and a cover said cover having a reduced central opening, a removable closure for said opening, and an inner tube of paper open vat top and bottom and split longitudinally said inner tube being capable of being coiled to reduce its diameter sufficiently to enable the tube to be inserted through said central opening in the cover and then to expand into contact with the inner wall of the outer tube, said inner tube being of less length than the outer tube and having its top edge, when the tube is expanded, positioned under the cover and outside of the plane of the walls of the opening therein.

Signed at Middletown, in the county of Orange, and State of New York, this 14th day of November, A. D. 1905.

EDWARD D. TOMPKINS.
